BOX.

Application led July 17, 1922. Serial. No. 575,683.

To all whom t may concern:

Be it known that I,HARR1soN B. WAnmn, a citizen of the United States,and a resident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements in Boxes; and I do herebydeclare that the following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecilication.

This invention relates to improvements aper board and consists of thematters hereinafter described and more particularly pointed out in theappended claims.

The invention relates more particularly to the type of box shown inLetters-Patent No. 1,055,243 granted to meA on March 4th, 1913, whichconsists of a body made from a blank cut and creased to'fold intotubular form and of ends or heads made from blanks each cut and creasedto provide the head and foldable flaps at the sides of the head, whichare adapted to be attached to the sdes of the bod with the head partsrecessed within the tubular ends of the body.

The object of the invention is to improve and strengthen a box of thekind and in particular to so form the heads that the rigidity of thev.box at or in the neighborhood of its heads or ends will be greatly in-1creased Vas compared to prior boxes of the ind.

This and. other advantages of the invention will appear more fully as Iproceed with my specification.

In the drawings Fig. 1, is a view representing the improved box inperspective.

Fig. 2. is a plan view of the blank for forming a head of the box.

Fig. 3 is a view representing on an enlarged scale an elongated sectionthrough the head blank in a plane indicated by the line 3 3 of Fig. 2.

Fig. 4 is a detailed sectional view on a still larger scale ina planeparallel .to one side of the box, Ashowing the head and the iap at oneedge thereof folded up in the position it occupies when the head isinserted in the end of the box. v

Fig. 5 is a similar section showing the same parts as they appear whenthe ap Fig. 6 is a detailed sectional view showing I the result offolding the flap in the wrong wa geferring now to that embodiment of theinvention illustrated in the drawings 10 indicates the box whichcomprises a tubular body 11 and recessed heads 12-12. The tubular bodyis made from an elon ated blank cut and creased to fold into tu ularform and provide the four sides 13, 14, 15 and 16 of the box and, asshown, an extension 17 on one of the sides which is adapted to be foldedover upon and to be secured to the side 16 when forming and closing thetube. l

Each head 12 is made from a blank cut and creased to provide the mainbody of the blank and flap extensions 18 at all sides of the blank-said,iap extensions being' defined by the creases 19 which outline the sidesof the main part of the blank. Right angle notches 20 are cut at thefour corners of the blank so thatV the flaps 18 may be turned up intoplanes at right angles to the plane of the head with the ends of theiaps in lines parallel to the corners of the tubular box body.

In forming the creases in the blanks, to permit the folding asdescribed, male and female die members are used which produce a deepcomparatively wide groove 21, as shown in Fig. 3. The material of theblank is correspondingly upset on the opposite side in the form of a rib22.

In constructions of boxes of the kind heretofore, it has been customary,particularly in the'case of the head blank, to fold the iiaps at theedges of the head blank in such manner as to open the groove 21 Wider soas to present the base of the groove outwardly at the corner of thefold, crowding the material in the rib 22 upon itself,-as shown in Fig.6. It has been found, however, that this folding of the flap tends togreatly weaken the head adjacent the a and in particular that the stockin the ri was opened up and spread apart into a plurality of spacedlayers of stockas indicated at 23 in Fig. 6.

Again it has been found that' in folding the flap inthis manner, therewas no definite and ysure location of the line which would form the axisupon which the iiap roove 21 presented inwardly, as shown in igs. 4 and5. A number of advantages will result from thus folding the flap.

In the first place, the flap may always be folded along the edge of therib farthest from the edge of the flap (as shown in the view referredto), with theV result that the de th of the flap will always be the sameang the depth of the recess may be accurately predetermined in allcases. Thus, the net inner length of the tubular bqdy of the box isalways the same and may be made to accord with specifications. Theobjectionable distortion and separation into layers of the stock in theneighborhood of the rib as shown in Fig. 6 and the resultant` weakeninof the flap at this point is done away wit And in addition, the Hap isin effect folded up against a shoulder extendin along the edge of thebox head as the resu t of colla sing the groove 21 upon itself infolding tlie flap, so that a very strong and rigid head construction isproduced when the flap is secured to the adjacent side vwall of the box,as shown in Fig. 5.

While in describing and illustrating the invention I have shown it asapplied to a form of box which is known as an end loader, asdistinguished from a top loader, it will be manifest that the inventionis in no way limited to a box of the kind, since the body of the box maybe set up in any familiar manner and the flap 17 and the side 16, towhich it is attached, may be relatively proportioned so as to overlap inany desired way and -may be attached together in the beginning as in thecase of an end loader or may be attached together and to the flaps ofthe heads, after the box is loaded,-the other sides having been attachedto the flaps of the heads before loading; as may be desired or as maymeet the particular purpose for which the box is designed.

Again the construction, though designed as shown herein for a singlecpiece or solid head box, is capablel of use in any box where thehead'consists in whole or in part of a blank cut and creased to providea head or head part and a flap adapted to be folded at right anglesthereto and to be attached to the side wall of the box.

I claim as my inventioni 1. In a box made of fibre or paper board,

cessed head for an end of said havin a tubular body and a head closingan en of said body, said head includinga blank cut and creased toprovide a head part and a flap part, the crease presenting a roove onone side of the blank and a rib beow the crease on the other side of theblank, the flap being folded at right angles to the plane of the head,with the groove in the lnner angle of the fold andhaving its bottomsurface en aged with that side of the roove remote rom said fiap part,the rib eiig located at 4the'outer an le of the fold and the flap beingattached fizat against the adjacent side of the tubular body.

2. In a box made of fibre or paper board, having a tubular body and arecessed head closing' an end of said body, said head including a blankcut and creased to provide a head part and a flap part, the creaseresenting a groove on one side of the b ank and a rib below the creaseon the other side of the blank, the flap being folded at right angles tothe plane of the head, with the groove in the lnner angle of the foldand having its bottom surface engaged with that side of the grooveremote from said ap part, the rib being located at the outer angle ofthe fold, and the flap attached flat against the adjacent side ofthetubular body.

3. In a box made of fibre or a r board, in comblnation with a tubularbio y, a head for an end of said body, said head being made from a blankcut and creased to rovide a head part and flap parts at the our sides ofsaid head part, the creases presenting grooves on one side of the blankand ribs el'ow the creases on the other side of the blank, each flapbeing folded at right angles to the plane of the head, with the groovein the lnner angle of the fold and having its bottom surface. engagedwith that side of the groove remote from said ap part, the rib beinglocated atv the outer angle of the fold, and each flap being attachedflat ginst the adjacent side of the tubular 4. In a box made of fibre orpaper board, in combination with a tubular body, a rey, said head beingmade from a blank cut and creased to provide a head part and flap partsat the four sides of said head part, the creases presenting grooves onone side of the blank and ribs below the creases on the other side ofthe blank, each fiap being folded at right angles to the plane of thehead, with the groove in the inner angle of the fold and having itsbottom surface engaged with that side of the groove remote from said appart, the rib being located at the outer angle of the fold, and eachflap bein attached flat against the adjacent side of the tubular body.

in combination with a tubular body, a head for an end of said bodysaidhead being made from a blank cut and creased to provide a head part andi'lap parts at the :four sides of said head part, the creases presentinggrooves on one side of the blank and ribs below the creases on the otherside of the blank, each flap being folded at'right angles to the planeof the head,\with the groove in the inner angle of the fold and havingits bottom surface engaged with that side of the groove remote fromSaid" flap part, the rib being located at the outer angle of the fold,and each flap lbeing attached flat against the adjacent side of thetubular 15 body, and the head part abutting at its edges against the Happarts.

In testimony that I claim the foregoing as my invention, I atiix mysignature in the presence-of two witnesses, this 13th day of 20 Ju1y,A.D. v1922.
